The complete chloroplast genome of an endangered orchid Paphiopedilum spicerianum.

ABSTRACT: Paphiopedilum spicerianum (H. G. Reichenbach) Pfitzer is an endangered and threatened orchid species in China. The genetic and molecular data of this orchid species is deficient. With the aim to identify appropriate chloroplast markers for the use in a conservation biology study, the complete chloroplast genome of P. spicerianum was reported. We found that the chloroplast genome of P. spicerianum is 157,292 bp in length, containing a large single-copy region of 87,252 bp, a small single-copy region of 1828 bp, and a pair of inverted repeats of 34,106 bp. Genome annotation predicted 105 unique genes, including 71 protein-coding genes, 30 tRNAs, and four rRNAs. Fourteen genes contained one intron and two genes (clpP and ycf3) had two introns. The GC content of the P. spicerianum was 35.8%. Phylogenetic analysis indicated P. spicerianum was closely related to P. purpuratum.

Complete Chloroplast Genome of Paphiopedilum delenatii and Phylogenetic Relationships among Orchidaceae.

Project description:Paphiopedilum delenatii is a native orchid of Vietnam with highly attractive floral traits. Unfortunately, it is now listed as a critically endangered species with a few hundred individuals remaining in nature. In this study, we performed next-generation sequencing of P. delenatii and assembled its complete chloroplast genome. The whole chloroplast genome of P. delenatii was 160,955 bp in size, 35.6% of which was GC content, and exhibited typical quadripartite structure of plastid genomes with four distinct regions, including the large and small single-copy regions and a pair of inverted repeat regions. There were, in total, 130 genes annotated in the genome: 77 coding genes, 39 tRNA genes, 8 rRNA genes, and 6 pseudogenes. The loss of ndh genes and variation in inverted repeat (IR) boundaries as well as data of simple sequence repeats (SSRs) and divergent hotspots provided useful information for identification applications and phylogenetic studies of Paphiopedilum species. Whole chloroplast genomes could be used as an effective super barcode for species identification or for developing other identification markers, which subsequently serves the conservation of Paphiopedilum species.
